PROCESS FOR RECOVERING CADMIUM FROM CADMIUM-PLATING ELECTROLYTE WASH WATER

摘要

Usage: the invention relates to methods for extracting cadmium from cadmium-free cyanide-free electrolyte wash water. Essence: a plate of low-alloyed magnesium alloy is placed in a case of a chemically resistant fabric, the case with a plate of a metal-cementing agent is dipped into the cadmium electrolyte wash water solution and the cadmium is extracted by cementation at a pH of 5-8. 1 tab.
